Title: Method and device for the lining of linear materials with textile fibres
Inventor: RUSEV RUMEN A
IPC: D07B7/14
Filed: 1990-04-03
Abstract: The method and the device are applicable for obtaining yarns and cable bandaging of various fibres. They help optimising the material consumption and obtaining yarns with an impressive shape with a simple mechanical system and possibilities for parameter change with ease. With this method, the loop of the first lining thread is shoved through the loop of the last one and is kept in this position. Then, the loop of the second lining thread is shoved through the loop of the first one and is kept in this position, meanwhile the last lining thread is drawn in the working zone. The process is kept in this sequence and then it is repeated. The device includes electromagnets with two sections the anchor of which represent a hollow barrel. The lining threads are respectively shoved in a tension bar, a photo-sensor, the respective electromagnet anchor and an eye, and the main thread - with two other photo-sensors and two eyes. The electromagnets are put into a control scheme including a clock-pulse generator, connected through a repeater to three starting positions with two circle counters. The outlets of the counters are connected in a particular way, respectively through an OR gate, inverters and thyristors to the electromagnet sections.<IMAGE>

Title: Method of making a sulfonate ester and cross-linked alcohol coated support matrix
Inventor: JOHNSON SUSAN S
IPC: C07K17/08
Filed: 1989-12-04
Abstract: "METHOD OF MAKING A SULFONATE ESTER AND CROSS-LINKED ALCOHOL COATED SUPPORT MATRIX"                          ABSTRACT           A support matrix generally useful for the immobilization of biologically active proteins is made by coating a core support with a polymeric alcohol where the core support is titania or titinated alumina or a carbonaceous pyropolymer deposited on a high surface area refractory inorganic oxide, cross-linking the alcohol contained in the resulting coated support;  and thereafter converting a portion of the hydroxyl moieties of the resulting crosslinked alcohol coated support to sulfonate esters.  Such coated support matrix covalently bind enzymes and antibodies via a strong carbon-nitrogen single bond to give, for example, an immobilized antibody system extremely resistant to leaching of the antibody, the cross-linked alcohol, or of metals from the core support.

Title: Expression induction method
Inventor: LO KIN-MING
IPC: C12N15/67
Filed: 1989-12-05
Abstract: Disclosed is a method of producing increased amounts of a protein of interest in a cell by induction.  The method includes transfecting a cell with multiple copies of an expression vector, each copy of which includes an espressible gene encoding an enzymatically functional dihydrofolate reductase (DHFR) and an expressible gene encoding a protein of interest.  Transfected cells are cultured in the presence of methotrexate (MTX) to produce a plurality of clones.  A clone containing plural copy number of the vectors which co-express DHFR and the protein of interest is then selected and cultured,  The cultured clone is treated with MTX to enhance the expression of the protein of interest by inducing an increase in transcription without substantially amplifying the genes encoding the protein of interest and DHFR.

Title: Method for delivering pulp onto the wire of a paper machine
Inventor: KUNNAS AINO
IPC: C02F3/34
Filed: 1990-01-15
Abstract: (57) ABSTRACT OF THE DISCLOSURE            The invention concerns a method for delivering pulp onto the wire of a paper machine into a sheet which in the later stages in converted into finished paper. The thick pulp from the pulping process is suspended with the white water recirculated in the paper machine into a suspension, which is delivered onto the wire into a homogeneous sheet and from which the water drained through the wire is recirculated  to  the  suspension  process.  The  closed circulation allows the enrichment of constituents such as hemicellulose dissolved or dispersed from the stock being prepared  that  lower  water  drainage  and  degrade  the retention of fibers. According to the invention, enzymes are added to the lean white water of low consistency that are   capable   of   disintegrating   said   deleterious constituents.  The  enzyme  can be  added  to  the  short circulation of lean white water taking place from the sheet forming on the wire to the suspension process of the pulp,  or alternatively, to the long circulation of the white  water  to  other  locations  of  use  in  the  paper machine.  The  invention  is  particularly  applicable  to papermaking based on mechanical pulp such as TMP in which the amount of hemicellulose dissolving in the white water is highest.

Abstract: PHQ 89.003 ABSTRACT         METHOD OF DETERMINING THE MONITOR SENSITIVITY OF, AND METHOD AND SYSTEM FOR CONTROLLING A RADIATION EMITTING ARRANGEMENT, AND OPTICAL RECORDING   AND/OR REPRODUCING APPARATUS INCLUDING SUCH A SYSTEM    A method is described which enables automatic determination of the monitor sensitivity of a radiation emitting arrangement (in particular a laser diode and photodiode arrangement), which monitor sensitivity relates a level of a monitor signal (IM) generated by the arrangement to a corresponding optical output level (OL) of the arrangement.  The method comprises the steps of: (i) supplying a varying drive signal (IL1,IL2) to the arrangement and measuring the rate of change (.DELTA.IM/.DELTA.IL) of the monitor signal (IM) with respect to the supplied drive signal (IL); and (ii) combining the measured rate of change with an assumed differential efficiency (k) of the arrangement to determine the monitor sensitivity (OL/IM) of the arrangement.  The provision of a control system able to implement such a method can eliminate the need for a factory adjustment in the maufacture of apparatus such as optical recording and/or reproducing apparatus.

Abstract: A disk drive having a base  (1)  and a cover  (12), enclosing the memory disks  (3)  and the magnetic head (8) actuator (5,6,7).  The spindle (2) journaling the memory disks (3) and the support (4) for the actuator (5,6,7) are secured to the base (1) and to the cover (12).  The materials of the base (1), the cover (12), the spindle (2) and the support (4), have thermal coefficients of expansion which are at least substantially the same.   Preferably the materials are the same.   Steel  is a preferred material.   The design also provides rigidity between the ends of the rotary mounting (2) of the memory disks and the support (4) for the magnetic head (8)  actuator  (5,6,7)  while providing  flexibility  in the connections between the base (1) and cover (12), and thereby eliminating thermally induced slip at these connections.  Slip between structural parts of a disk drive can prevent reliable writing and reading of data.
